<h3>NUKIDevice</h3>
<ul>
  <u><b>NUKIDevice - Controls the Nuki Smartlock</b></u>
  <br>
  The Nuki module connects FHEM over the Nuki Bridge with a Nuki Smartlock. After that, it´s possible to lock and unlock the Smartlock.<br>
  Normally the Nuki devices are automatically created by the bridge module.
  <br><br>
  <a name="NUKIDevicedefine"></a>
  <b>Define</b>
  <ul><br>
    <code>define &lt;name&gt; NUKIDevice &lt;Nuki-Id&gt; &lt;IODev-Device&gt;</code>
    <br><br>
    Example:
    <ul><br>
      <code>define Frontdoor NUKIDevice 1 NBridge1</code><br>
    </ul>
    <br>
    This statement creates a NUKIDevice with the name Frontdoor, the NukiId 1 and the IODev device NBridge1.<br>
    After the device has been created, the current state of the Smartlock is automatically read from the bridge.
  </ul>
  <br><br>
  <a name="NUKIDevicereadings"></a>
  <b>Readings</b>
  <ul>
    <li>state - Status of the Smartlock or error message if any error.</li>
    <li>lockState - current lock status uncalibrated, locked, unlocked, unlocked (lock ‘n’ go), unlatched, locking, unlocking, unlatching, motor blocked, undefined.</li>
    <li>succes - true, false   Returns the status of the last closing command. Ok or not Ok.</li>
    <li>batteryCritical - Is the battery in a critical state? True, false</li>
    <li>battery - battery status, ok / low</li>
  </ul>
  <br><br>
  <a name="NUKIDeviceset"></a>
  <b>Set</b>
  <ul>
    <li>statusRequest - retrieves the current state of the smartlock from the bridge.</li>
    <li>lock - lock</li>
    <li>unlock - unlock</li>
    <li>unlatch - unlock / open Door</li>
    <li>locknGo - lock when gone</li>
    <li>locknGoWithUnlatch - lock after the door has been opened</li>
    <br>
  </ul>
  <br><br>
  <a name="NUKIDeviceattribut"></a>
  <b>Attributes</b>
  <ul>
    <li>disable - disables the Nuki device</li>
    <li>interval - changes the interval for the statusRequest</li>

<h3>NUKIDevice</h3>
<ul>
  <u><b>NUKIDevice - Steuert das Nuki Smartlock</b></u>
  <br>
  Das Nuki Modul verbindet FHEM über die Nuki Bridge  mit einem Nuki Smartlock. Es ist dann m&ouml;glich das Schloss zu ver- und entriegeln.<br>
  In der Regel werden die Nuki Devices automatisch durch das Bridgemodul angelegt.
  <br><br>
  <a name="NUKIDevicedefine"></a>
  <b>Define</b>
  <ul><br>
    <code>define &lt;name&gt; NUKIDevice &lt;Nuki-Id&gt; &lt;IODev-Device&gt;</code>
    <br><br>
    Beispiel:
    <ul><br>
      <code>define Haust&uuml;r NUKIDevice 1 NBridge1</code><br>
    </ul>
    <br>
    Diese Anweisung erstellt ein NUKIDevice mit Namen Haust&uuml;r, der NukiId 1 sowie dem IODev Device NBridge1.<br>
    Nach dem anlegen des Devices wird automatisch der aktuelle Zustand des Smartlocks aus der Bridge gelesen.
  </ul>
  <br><br>
  <a name="NUKIDevicereadings"></a>
  <b>Readings</b>
  <ul>
    <li>state - Status des Smartlock bzw. Fehlermeldung von Fehler vorhanden.</li>
    <li>lockState - aktueller Schlie&szlig;status uncalibrated, locked, unlocked, unlocked (lock ‘n’ go), unlatched, locking, unlocking, unlatching, motor blocked, undefined.</li>
    <li>succes - true, false Gibt des Status des letzten Schlie&szlig;befehles wieder. Geklappt oder nicht geklappt.</li>
    <li>batteryCritical - Ist die Batterie in einem kritischen Zustand? true, false</li>
    <li>battery - Status der Batterie, ok/low</li>
  </ul>
  <br><br>
  <a name="NUKIDeviceset"></a>
  <b>Set</b>
  <ul>
    <li>statusRequest - ruft den aktuellen Status des Smartlocks von der Bridge ab.</li>
    <li>lock - verschlie&szlig;en</li>
    <li>unlock - aufschlie&szlig;en</li>
    <li>unlatch - entriegeln/Falle &ouml;ffnen.</li>
    <li>locknGo - verschlie&szlig;en wenn gegangen</li>
    <li>locknGoWithUnlatch - verschlie&szlig;en nach dem die Falle ge&ouml;ffnet wurde.</li>
    <br>
  </ul>
  <br><br>
  <a name="NUKIDeviceattribut"></a>
  <b>Attribute</b>
  <ul>
    <li>disable - deaktiviert das Nuki Device</li>
    <li>interval - verändert den Interval für den statusRequest</li>
    <br>
  </ul>
</ul>
